Abstract (en)

[origin: EP0798315A1] A process for the production of homogeneous mixtures (I)containing (a) metallocene(s), (b) co-catalyst(s) and (c) formulation media, in which the preparation of the catalyst system (a + b) comprises: (A) direct preparation by known methods in the hydrocarbon used (HC), or (B) suspending, dispersing or dissolving the isolated metallocene-based catalyst components in HC, or (C) adding a solution of the components in low-boiling solvent (made by known methods) to HC and then removing the low-boiling solvent, optionally with the use of (D) conventional inorganic or organic support materials, auxiliary substances and/or additives etc. Also claimed is a formulation obtained by this process.

Abstract (de)

Die Erfindung betrifft ein Verfahren zur Herstellung von homogenen, hochaktiven, stabilen Formulierungen, bestehend im wesentlichen aus einer oder mehreren metallorganischen Katalysatorkomponenten in Paraffinen, sowie gemäß diesem Verfahren hergestellte Formulierungen.
